DUPLEX-ENVELOP.

SPECIFICATION forming part of Letters Patent No. 696,225, dated March25, 1902. Application filed January 13, 1902. Serial No. 89,442. (Nomodel.)

ToaZZ wwm, t .may concern:

Be it known that I, ARTHUR BENJAMIN COWLES, a citizen of the UnitedStates, residing at Richmond, in theV county of Henrico and State ofVirginia, have invented certain new and useful Improvements in DuplexEnvelops, of which the following is a specification.

The type of envelop which I have improved 1o is of the duplex form,designed to contain for distribution offerings for the support of thechurch and separate offerings for kindred purposes and which aredesignated on separable parts of the envelop, each offering being sealedin its separable part, so that each oifering may be applied as intended,and my improvement will be set out in the claim appended hereto inconnection with the accompanying drawings, in which- Figure l shows thepaper blank from which lthe envelop is formed. Fig. 2 shows the envelopWith its side folds or overlaps sealed to form the back of eachseparable part and the initial tear-cuts in the opposite edges. Fig. 3shows the envelop with the side folds of one only of its compartmentssealed. Fig. 4 shows the back of the sealed duplex envelop with onecorner at the initial tear-cut turned up. Fig. 5 shows the envelop withits sepa- 3o rable parts having printed thereon the pur-A pose oftheseparate oerings.

The separate envelops l l are connected in the blank end for end, theopposite end of each terminating in a sealing-Hap 2 2. Outs 3 3 are madein the opposite edges of the blank to form a separate back fold 4 4 foreach envelop, and these cuts extend partially across the front, leavingaligament 5, which, it willbe noted, is only in the front part of 4o theenvelop. VIt is this ligament which `connects the envelops end for endand forms the separable tear part, so that the tear is in the front onlyof the envelop. At the cut each side fold is gurnmed on`its inner sideat 6 and the side edge of one of theside folds is gummed at 7, so thatwhen the side folds are closed with each other they are sealed with a.lap-seam 8, and the ends of these lapped side folds are sealed with thefront along the cut 5o and along and over the ligament.

Looking now at Fig. 2, it is seen that the sealed edges of the sidefolds abut with each other and form a sort of groove 9 between them, andit is this groove which forms a sort of guideway in the line of theinitial cuts and over the ligament, thereby keeping the tear between theabutting edges of the side laps, so that any diversion of the 'tear intoor through the sealed end of either envelop is prevented. Moreover, byhaving the liga- 6o ment in the front only the tear is rendered moreeasy than if it was through the two gummed thicknesses of the front andback. To render the tearing apart of the sealed envelope easy, certain,and quick is the purpose of my improvement, and it will be noted thatthe tear is only through the front integral part between the abuttingedges of the sealed side folds, and as this integral part need not begummed the tear can only be 7o through the ungummed integral part, sincethe side folds only are gummed to the front between their abuttingedges. By gumming the abutting edges of the side folds they are therebysealed toL the front, leaving the line across the ligature between saidabutting ends open. Therefore the ligature can be sufficiently wide tohold the connected parts in symmetrical relation. In making the tear@the abutting sealed ends are spread apart at 8o the cut edge, and thetear commences at the ligament and severs the parts in the groovevformed between the abutting ends, so that the tear starts not at theedge, but near the middle of the width of the envelop.

As seen in Fig. 4, each of the connected envelop parts may bear the sameor a differ ent number and each part have certain printed wordsindicating the purpose of the offering and the date thereof. 9o

To facilitate the tearing, the cuts may be made V shape in the edges, asseen in dotted lines in Figs. l, 2,'and 3; but these V-shaped cuts mustbe within the gummed strips 6 6, so as not to uncover the joining sealedends of the envelops.

I claim- A duplex envelop comprising a pair of compartments joined endfor end ,the back folds being gummed and cut at 3 said cuts extendrooing into but not across the front forming In testimony whereof I afx mysignature thereby the separate beek folds 4 4, and conin presence of twowitnesses. fining the tear for separating the compartments to Ithe uncutfront part 5 between the 5 ends of said outs, the abutting,r edges ofsaid Vtnesses:
